1EZ100D/TR8

Overview

The 1EZ100D/TR8 is a single Zener diode manufactured by Microsemi Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes a DO-204AL (DO-41) axial through-hole package. Key electrical characteristics include a forward voltage of 1.2 V at 200 mA and a reverse leakage current of 10 µA at 1 V. It operates within a temperature range of -65°C to 150°C.

Feature Summary

• Provides precise voltage regulation with a 5% tolerance on the 100 V Zener voltage.
• Capable of handling high DC currents or full power ratings when equipped with adequate heat sinking.
• Features Level 1 moisture sensitivity classification, eliminating the need for dry packaging.

Applications

• Voltage reference circuits requiring stable 100 V levels.
• Overvoltage protection in electronic systems.
• General-purpose voltage regulation in industrial equipment.

Procurement Notes

Verify component authenticity as this part may be obsolete. Confirm RoHS compliance status, as standard versions are non-compliant while e3 variants exist. Check for lead-free alternatives if environmental regulations require it. Ensure the specific suffix matches the required tolerance and packaging format for your design.

Selection Notes

Select this component for designs requiring a robust 1 W axial Zener diode with strict 5% voltage accuracy. Consider the DO-41 package constraints for PCB layout. Evaluate thermal management requirements given the 1 W power rating. Verify that the operating temperature range meets the environmental conditions of the target application.
